Prof. Dr. Robert Arlinghaus erforscht als Sozialökologe die komplexen Wechselwirkungen zwischen menschlichem Verhalten und ökologischen Systemen, mit einem Schwerpunkt auf nachhaltiger Freizeit- und Berufsfischerei. Seine Arbeit verbindet naturwissenschaftliche Methoden wie Verhaltensbeobachtung und Modellierung mit sozialwissenschaftlichen Ansätzen, um Governance-Strukturen und Managemententscheidungen zu optimieren. Ein zentrales Anliegen ist die transdisziplinäre Wissensko-Produktion mit Stakeholdern sowie die effektive Wissenschaftskommunikation, um gesellschaftliche Akzeptanz und nachhaltige Praktiken zu fördern. Zudem untersucht er evolutionäre Anpassungen von Tierpopulationen an anthropogenen Selektionsdruck und Fragen des Tierwohls.

• Understanding the Complexity of Catch-and-Release in Recreational Fishing: An Integrative Synthesis of Global Knowledge from Historical, Ethical, Social, and Biological Perspectives

  2007

  Reviews in Fisheries Science · DOI

  Most research on catch-and-release (C&R) in recreational fishing has been conducted from a disciplinary angle focusing on the biological sciences and the study of hooking mortality after release. This hampers understanding of the complex and multifaceted nature of C&R. In the present synopsis, we develop an integrative perspective on C&R by drawing on historical, philosophical, socio-psychological, biological, and managerial insights and perspectives. Such a perspective is helpful for a variety of reasons, such as 1) improving the science supporting successful fisheries management and conservation, 2) facilitating dialogue between managers, anglers, and other stakeholders, 3) minimizing conflict potentials, and 4) paving the path toward sustainable recreational fisheries management. The present work highlights the array of cultural, institutional, psychological, and biological factors and dimensions involved in C&R. Progress toward successful treatment of C&R might be enhanced by acknowledging the complexity inherent in C&R recreational fishing.

• Documented and Potential Biological Impacts of Recreational Fishing: Insights for Management and Conservation

  2006

  Reviews in Fisheries Science · DOI

  While the impacts of high exploitation on fish populations and aquatic ecosystems are well-documented for commercial fishing, particularly in the marine environment, the potential biological impacts of angling received less attention. This paper discusses angling patterns within a framework of basic ecological and evolutionary literature and examines potential biological impacts of angling by focusing on study results associated with high exploitation rates and pronounced selective exploitation. The impacts range from impacts occurring directly on the exploited species (truncation of the natural age and size structure, depensatory mechanisms, loss of genetic variability, evolutionary changes), to those that occur on the aquatic ecosystem (changes in trophic cascades, trait-mediated effects). As a third category, impacts related to the angling activity per se are distinguished (habitat modifications, wildlife disturbance, nutrient inputs, loss of fishing gear). Although the main threats to fish often are localized outside recreational fisheries, there is growing evidence that angling and angling associated activities can lead to a decline of fish populations and affect aquatic ecosystems in various ways provided that the degree of the fishing mortality is high and the selective exploitation is intensive. Inconclusion, management implications for sustainable recreational fisheries and areas for future research are outlined.
